What ImageOptim is
ImageOptim API is a service for optimizing images, with batch processing, resizing, and metadata controls. It supports JPEG, PNG, SVG, and GIF, and offers both compression modes. Users can connect their own CDN or infrastructure through the POST API to store and serve images. The service lists a free plan and a free trial. Paid monthly plans are $12 a month for 2,000 optimizations, $49 a month for 16,000, and $245 a month for 100,000. Cached requests are free, and serving the same image to 1,000 users counts as one optimization. Traffic continues to be served after an optimization allowance is exhausted. ImageOptim identifies the API as its product, and using it requires agreement to its terms of service. The listed API upload limit is 50. API access is available, and the platform listing is API.
